inter-word

English decided to make some interesting trade-offs in expected word order to lower redundancy in inter-word agreement morphology.

The set of features that cause this type of inter-word agreement are called phi features (typically count, gender, person, and case).

Two spaces is a sensible convention for distinguishing inter-word spaces from inter-sentence spaces.

The high resolution display is probably great, but look at that inter-word spacing!

It's also where line-width and inter-word padding are corrected first so often ends up being at least as big a space as you'd get double-spacing anyway.

It feels like it helps to build the inter-word connections.

Ragged right lends itself to much cleaner inter-word spacing.

The post sentence spacing was never really treated as two consecutive spaces - conceptually, it's a single area of whitespace that is larger than the inter-word spacing.

I have seen so many AI narrations where it reads the dash exactly like a hyphen, actually maybe slightly reducing the inter-word gap.

I can specify inter-word justification, but there are cases where getting the spacing just right is impossible without breaking a long word using a hyphen.

For that matter, I don't think CSS can even do justification properly (by properly, I mean not treating each line as an independent unit, but shifting text around within an entire paragraph to minimize deviation from the desired inter-word spacing globally).

Teacher training courses tend to echo the 'sans for dyslexics' notion but in addition suggest the use of headings with space before and after and the use of bullet points to break up material, the use of right-ragged (for LTR languages) so that inter-word spacing remains constant, and the use of line spacing chosen so that the space between the lines is a bit longer than the spacing between the words.

One of the formatting options is "full justification" which adjusts the width of inter-word spacing to achieve smooth left and right margins.

For example the TeX engine does not associate the original space characters with the inter-word “glue” that replaces them, so pdfTeX happily omits them.
